Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

The sales of ruby as a per cent of the total sales of precious stones for the given period

(1) 17.3

(2) 19.23

(3) 23.1

(4) Cannot be determined

(5) None of the above

EVALUATION

Here from the graph we see that

The total sales of precious stones for the given period

= 1000 + 800 + 1400 + 1100 + 900

= 5200

Now the total sales of Ruby

= 200 + 300 + 200 + 200 + 100

= 1000

Hence the required sales of ruby as a per cent of the total sales of precious stones for the given period

$\displaystyle \sf{ = \frac{1000}{5200} \times 100 \%}$

$\displaystyle \sf{ = \frac{1000}{52} \%}$

$\displaystyle \sf{ = 19.23 \: \%}$

FINAL ANSWER

Hence the correct option is (2) 19.23
